Doodle Labs

DL915-26 is a state-of-the-art OFDM radio transceiver for the 902-928 MHz frequency band to deliver IP based Video, Voice and Data services in Near Line of Sight (NrLOS) conditions. It features high data throughput with up to 1W Tx power, better Rx sensitivity and high SNR. DL915-26 is specially designed to deliver best performance in long-range outdoor applications. It features advanced filtering and noise reduction techniques for high interference immunity from the neighboring Pager and GSM transmitters. In the field, DL915-26 is proven to provide the best performance amid co-located powerful base stations. The DL915-26 has demonstrated the ability to provide high throughput even in noisy environments where competitor products fail to operate in side-by-side comparisons.

DL915-26 features Doodle Labs’ proprietary Prism^TM hybrid heterodyne RF technology with advanced filtering and noise reduction techniques for high interference immunity. DL915-26 maintains distortion free signal at higher modulation rates to maintain low packet errors and maximizes data throughput. The design uses highly linear power amplifiers to deliver maximum power even at 64 QAM radio modulations while maintaining low EVM (Error Vector Magnitude). The DL915-26 employs fine tuned Low Noise Amplifier on the the receive chain to obtain better Rx sensitivity and high SNR. DL915-26 is specially designed to deliver best performance in long-range outdoor applications. The Industrial/Military grade design & enhanced resilience to RF surges & ESD makes it ideal for deploying in harsh environments.
